Intermittent orthographic stereo projection problems

[AySz88]

Yes - the center of the object is at the same distance as the screendistance used for the orthographic projection. Thus the square mark should always have zero disparity, so it shouldn't move no matter what the IPD is.

Does that line of code force the IPD value to zero? That wouldn't work for my purposes, since I do need stereo - it is adjusting the IPD value so as to "turn up" or "turn down" the stereo cue on demand, as needed by the rest of the experiment.

The IPD vector is used by vizcave to change the direction the IPD shift is applied to the view matrix. I think adding that line should fix your problem.
